Training:

• download the data from https://uni-bonn.sciebo.de/s/3Wyqu3cxYSm47Kg.
• extract it so that you have the data folder in the same directory as main.py.
• To train the model on split1 of Breakfast dataset run python main.py --model=MODEL --action=train --vid_list_file=./data/train.split1.bundle where MODEL is cnn or rnn.
• To change the default saving directory or the model parameters, check the list of options by running python main.py -h.

Prediction:

• Run python main.py --model=MODEL --action=predict --vid_list_file=./data/test.split1.bundle for evaluating the the model on split1 of Breakfast.
• To predict from ground truth observation set --input_type option to gt.
• To check the list of options run python main.py -h.

Evaluation:

Run python eval.py --obs_perc=OBS-PERC --recog_dir=RESULTS-DIR. Where RESULTS-DIR contains the output predictions for a specific observation and prediction percentage, and OBS-PERC is the corresponding observation percentage. For example python eval.py --obs_perc=.3 --recog_dir=./save_dir/results/rnn/obs0.3-pred0.5 will evaluate the output corresponding to 0.3 observation and 0.5 prediction.
